I just purchased a used iPad 64gb with 3G, unfortunately the seller restored it to 4.3 (8F190) with modem firmware 07.11.00
As far as I can tell there is no way to jailbreak now, is this correct?
I am not planning on using the 3G just the wifi, would be great if I could downgrade and jailbreak or something like that.

Thanx, i'll check it out. I purchased a used iPad 1.
I got the wife a 64gb with 3G in like new condition with 2 months warranty still remaining and leather case for $360, can't go wrong.
Almost tempted to find another one for me instead of the iPad 2.
